Elastic Compute Service:Use Workbench to upload or download files

Last Updated:Dec 01, 2025

After you log on to an Elastic Compute Service (ECS) instance using Workbench, you can use the file management feature to upload or download files.

Usage notes

  • File size limit: You can upload a file of up to 1200 MB to a Linux instance or a file of up to 100 MB to a Windows instance. If the file size exceeds the limit, use other file transfer methods.

  • Transfer speed: File transfers using Workbench may be slow during peak hours. If you experience slow transfer speeds, you can use other file transfer methods.

  • This feature is not supported for session management connections from the console.

Upload files

Important

To upload multiple files, compress the files into a single compressed file, transfer the compressed file to the instance, and then decompress the file on the instance. For more information, see Compress and upload files.

  • Cause

    You may be connected to the instance using a session management connection. This feature is not supported for session management connections.

    If you are not using a session management connection, try to refresh the page or reconnect to the instance.

  • Solutions

A file fails to be uploaded from a local computer, and a "Permission Denied" error is reported

  • Symptom

    image

  • Cause

    The user that you use to log on to the instance may not have write permissions for the destination folder. This causes the file upload to fail. For example, this error occurs if you log on to the instance as the ecs-user user and upload a file to the /opt folder.

  • Solutions

    • Log on as the root user and upload the file.

      Log on to the instance again as the root user and upload the file.

      If you selected ecs-user as the logon username when you created the instance, you must set a password for the root user before you can log on to the instance as the root user. For more information, see Method 1: Reset the password of an instance online in the console.
    • Upload the file to the home directory of the current user.

      For example, if you log on to the instance as the ecs-user user, you can upload files to the home directory of the ecs-user user, which is the /home/ecs-user folder.
